Lava drains back into vent after final episode of lava fountaining,...

Lava drains back into the vent about 70 minutes after the 16th episode ended. This episode covered the entire lava lake with new lava; only part of the smaller west crater is visible in this view of the vent area. As the lava poured into the vent, large sections of the dark lake crust were pulled apart by the differential movement of the molten lava below. The river of lava flowing back into the depths of Kīlauea is about 60 m (200 ft) wide. The inner walls of Pu‘u Pua‘i cone glow where slides have bared the incandescent interior.
